Alternative titles and symbols : Craniosynostosis with lid anomalies; Michels syndrome; Oculopalatoskeletal syndrome;
Description : The term '3MC syndrome' encompasses 4 rare autosomal recessive disorders that were
previously designated the Carnevale, Mingarelli, Malpuech, and Michels syndromes,
respectively. The main features of these syndromes are facial dysmorphism that includes
hypertelorism, blepharophimosis, blepharoptosis, and highly arched eyebrows, which
are present in 70 to 95% of cases. Cleft lip and palate, postnatal growth deficiency,
cognitive impairment, and hearing loss are also consistent findings, occurring in
40 to 68% of cases. Craniosynostosis, radioulnar synostosis, and genital and vesicorenal
anomalies occur in 20 to 30% of cases. Rare features include anterior chamber defects,
cardiac anomalies, caudal appendage, umbilical hernia (omphalocele), and diastasis
recti (summary by Rooryck et al., 2011). - Genetic Heterogeneity of 3MC Syndrome 3MC
syndrome-2 (3MC2; 265050) is caused by mutation in the COLEC11 gene (612502). See
also 3MC syndrome-3 (248340).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the mannan-binding lectin serine protease-1 gene (MASP1, 600521.0001);
